Specification of Letters Patent.

Patented Aug. 13,1912.

Original application filed October 4, 1905, Serial No. 281,326. Dividedand this application filed March 8,

To all whom it may concern:

Be it known thatI, Mauro Sonncsanr, a.

thereon.

In describing the invention in detail, reference will be had to theaccompanying drawings forminga part of this specifieation, wherein likecharacters of reference denote corresponding parts, in the several viewsand in which- Figure 1 is a plan of the machine illustrating thecarriage feeding mechanism, the upper part of the carriage beingomitted; Fig. 2 is a vertical sectional view; Fig. 3 is an elevation ofthe rear orback part of the machine Fig. 4-is a perspective view of therear part of the machine showing the mechanism in inoperative position;and Fig. 5 is the same view showing the mechanism in'operative positionfIn the drawings, 4 denotes a key lever provided with 'a key 1; which,through its component parts, is intended to depress a type lever orhammer 13. The said hammer 13 is fulcrumed on a pivot 24 carried by anarm 20'on a suspension bar 16 suspended bars successive to from theupper part 1'.) of the frame of the machine by a screw 18 in uch amannenthat it'mayoscillate laterall This suspension ban 16 carries atits lower part a spacer 15 and a. small roller 21 onwhich bears thespacer of the adjacent bar.

On de ressing a key, and consequently the interme iate leverv'f, thespacer link 14 is drawn down and this rocks the spacer cam 15 in amanner to cause 1t to act on the adjacent roller 21-and move laterallythe sus-' pension bar 16 on which said roller is mounted. Evidently thiswill displace all of the that which has been displaced by the key, andalso the last suspension bar 35. The movemen'oof. the carriage whichcarries the paper ought obviously, to be proportional to the number ofkeys depressed. The power required for moving the carriage is suppliedby a spring inclosed-within a casmg or drum 52 (Fig. 3) which may bewound up by turning the arbor 56 which acts to wind the spring throughthe bevel wheels 54 and 55, and which is rotated either by means of akey 58, or by means of a pedal acting through a cord wound about a drum57 ratcheted on the arbor 56.

The drum 52 (Fig.2) is in one piece with a gear wheel 53, which gearswith a wheel 59, fixed on an arbor (30 and this arbor transmits withmotion to the-upper wheel 61, which latter gears with the rack 45 solidwith the carriage. In order to render-the movement of the carriagealways proportional to the number of type keys that may besimultaneously pressed, there is an arbor 39 (Fig. l) journaled at 40and 41, which has an arm.42, that is designed to raise or lift up adetent '43 (Fig. l) and a special dctent l l pivoted to the detent 43and capable of movement laterally thereof. On the said arbor39 are alsotwo armsv 46 through which the vertical movement of a transverse bar 47which has springs L8 that keep it' always pressed against the lever 7,gives place to the rotation of the arbor 39. From this it follows, thatwhen the type keys are n'essed down, and\with them the levers 7 thisobliges the detents and 44: to turn in a vertical plane and the detent44: will free itself from the teeth of the outer rack 45 the momentafter the detent43 shall have engaged them. This detent 43 being fixedagainst lateral play, prevents the rack and carriage from displacement,while the detent 44, being free, will allow a lateral displacement equalto that of the last suspension bar 35, that is to say toan extent equalto the sum of all the displacements caused by the spacers for example,two teeth as shown in Fig. 5. This displacement of the bar is allowed tothe detent M by levers 5t and 50, against which a spring 49 presses.

rack a moment after the special detent -14 is engaged anew therewith.

en the syllable written is the last one I of a word, it 'would suffice,in order to-sep' arate it fromltl 1e Word that is to follow, to",depress alrey which is not provided with a v itype'-hammer.
